Chapter 45 Hardness Test!

In the laboratory of the Academy of Military Sciences.

A group of people are looking at an irregular piece of metal.

Zhang Pingyuan took a deep breath. This small piece of metal took him several hours.

Fortunately for him, in the information Dean Shen gave him, there are extremely detailed procedures and casting methods.

Even so, with his ability, he almost failed in the first production!

If it is someone else, or wants to mass-produce, it is almost impossible.

Originally thought it was just a small piece of alloy, but with my own attainments in this field, I could completely complete it alone.

Now he also had to convene the teams of the alloy research and development departments in the Academy of Military Sciences to work together.

Zhang Pingyuan exhaled and said in a deep voice.

"Before formal research and development, we still need to conduct a simple test on this alloy."

Regarding the specific production process of the alloy and related documents, he directly submitted it to the team.

Countless people below saw the contents of the document, and the expressions on their faces at this moment were exactly the same as those of Zhang Pingyuan before.

This special and complex alloy is simply beyond their cognition.

But at this moment, no one dared to question the authenticity of this document.

First of all, Zhang Pingyuan is the director of the Academy of Military Sciences, and his prestige in the field of alloys is relatively well-known.

Secondly, the alloy in the file is now lying quietly in front of it.

This is not questionable.

Among the crowd below, a young researcher stood up and asked.

"Director Zhang, according to the test, the Rockwell hardness of this alloy has reached above 10?"

Zhang Pingyuan nodded quietly.

Grade 10 is the standard for measuring Rockwell hardness, and it will not be used in more accurate scientific research data.

For alloys, the Brinell hardness scale is usually used to measure the hardness level.

he said seriously.

"Well, according to the Brinell hardness scale."

"The hardness of this alloy is far beyond the measurement range of Brinell hardness!"

"Based on the current level of scientific research, further tests are needed for a more accurate measurement."

The sound fell, causing many researchers in the laboratory to be surprised.

"Exceeded the measurement range of the Brinell hardness scale?"

"This can only show that the hardness of this alloy is indeed extraordinary."

"The alloy can actually reach this kind of hardness?"

"..."

The noisy sound continued for a while, and then became much quieter.

Zhang Pingyuan nodded.

In the laboratory, most of them are Brinell hardness testers.

This kind of hardness test is mainly to leave a pressure on the material to be tested by steel balls.

Then test the hardness of the material according to the diameter of the root.

But on this piece of alloy, there is no way to leave any indentation.

The steel balls on the hardness tester almost exploded, and there was nothing they could do.

If you want to test the detailed hardness of this metal, you can only use Vickers hardness, which is widely used in industry.

In the crowd, a researcher suggested.

"Can I simply test the hardness of this alloy?"

The research team in the entire laboratory agrees.

An alloy of this strength is simply unique.

They were also very curious about how hard this alloy was!

"Yes." Zhang Pingyuan nodded, but did not reject the proposal.

Although the cost of this new type of alloy is high, it has not yet reached the sky-high price point.

Moreover, this alloy itself is used for experiments, even if it is damaged, there is no problem.

After the voice fell, a researcher couldn't help but started to do it.

He took out a key from his pocket, picked a relatively sharp key, and slid it back and forth on the smooth metal.

There was a "humming" friction sound.

Countless people around also showed incomparably curious expressions.

Although the existing data has reflected a certain degree of hardness, in people's hearts, there are some things that need to be "seeing is believing".

After the scientific researcher rubbed back and forth, some extremely fine metal particles appeared on the surface of the alloy.

Obviously, these poor metals did not come off the alloy, but the keys in his hand.

He blew gently, and the metal debris disappeared.

The incomparably smooth surface of the metal was once again revealed to everyone.

After zooming in and observing, it really did not exceed anyone's expectations.

"Sure enough, there are no scratches!"

"This metal is at least as hard as diamond!"

"..."

Everyone nodded in satisfaction.

The scientific researcher let out a sigh of relief and took the key back.

key?That was nothing more than a small fight.

How can it be possible to use this kind of thing to really test the hardness.

I saw him take out a box of diamond-shaped diamond needles from the general toolbox!

Of course, it has another name, Mohs hardness pen!
This is an extremely simple and crude method for hardness testing.

It is only necessary to scratch the metal surface to be tested with a diamond drill.

Based on the scratches on the surface, the hardness level of the metal can be calculated.

Before, the difference in hardness between the two materials was too large, and it was normal to have no scratches.

Immediately afterwards, the researcher directly slid the diamond needle on the metal surface.

Under everyone's eyes, the drill needle was constantly sliding back and forth on the alloy.

This kind of diamond needle can cut glass with incomparable ease.

Ordinary metal, leaving a deep line without any problem.

Countless people are curious about the results of this test.

Hardness level above ten?How much is it.

In fact, there is never a strict boundary.

Because of the hardness of nature, most of them have corresponding ore or metal substitutes.

There are no protective measures and paint protection on the surface of this alloy.

Among the currently existing metals and alloys, no matter how high the hardness is.

As long as the hardness levels of the two are close, there will be some scratches.

For example, a diamond drill with a Mohs hardness of eight can also leave marks on a diamond with the same hardness of ten.

Even knives and steel are fine.

Some sharp utensils will produce some scratches after friction.

Soon, the test is over.

After zooming in through the instrument, on the electronic screen, the extremely smooth alloy surface shocked everyone.

It doesn't matter that there are no scratches on the surface of the alloy, but there are still debris left by the Mohs hardness pen on the alloy.

That's a diamond!

In the current nature, there is basically no metal that he cannot leave scratches on.

But the special alloy in front of him did it!
There was also a shocking sound in the laboratory.

"There are no traces!"

"how can that be!"

"A diamond needle doesn't leave a trace."

"That shows one thing, the two are not at the same level of hardness!"

"In other words, the hardness of this alloy is far greater than grade ten!"

"According to the current hardness classification, the hardness of this alloy is at least twelve, or even above grade thirteen!"

"..."
